REME machinery lorries - designation of Types

[Gary_GJK]

I've been looking for a contemporary source identifying the various types of REME machinery lorries without success. The War Establishments for REME Workshops show these vehicles by their letter ID Type but this gives no clue as to the role they perform. The closest I've found is a Canadian publication at the below link, which seems to largely be in sync with British designations (page 140 of the PDF doc).

I know there was a great deal of commonality between Br/Cdn units and equipment but they were by no means identical. The ones of interest to me at the moment are those in the 2nd Line REME Workshops (serving Brigades and Corps Troops) -

Armament Section;
Type J - for recharging recuperators of artillery pieces
Type X - general workshop (RCEME equivalent was Type A)

Vehicle Section;
Type I30 - battery charging
Type M - MT workshop

Telecoms Section;
Type Z - wireless workshop

In the post VE-Day WEs, there's also a 15-cwt truck, machinery, Type "T", replacing a car, heavy utility, Type "T", both in the Telecommunication Section. I've not seen anything on these vehicles.

Any directions on where to find a list of the REME machinery lorries, or thumbs up or down for the above would be appreciated.

Cheers,

Gary
